+#!/bin/sh
+#
+# Trove used to run a version of Lorry Controller that wasn't a
+# daemon, but instead was invoked once a minute from a crontab owned
+# by the lorry user. When we upgrade to a version of Lorry Controller
+# that does run as a daemon, we need to disable the cronjob. This
+# script does that.
+#
+# The lorry user crontab may contain other jobs, so we can't just
+# willy-nilly delete the whole crontab. Instead, we remove the
+# specific line. The line looks like this:
+#
+#     */1 * * * * flock -x -n /home/lorry/lorry-controller-area/lockfile
+#     -c lorry-controller --work-area=/home/lorry/lorry-controller-area 
+#     --log=syslog --log-level=info --html-file=/home/lorry/lc-status.html
+#
+# Except, of course, all on one line.
